Many of the titles, however, are older classics from the 20th century, so casual movie watchers shouldn't necessarily fret. Instant Watcher has the full list of expiring titles here.

Netflix communications director Joris Evers provided Mashable with the following statement, saying that subscribers can expect the service to add 500 more titles to its catalogue on May 1.

Netflix is a dynamic service, we constantly update the TV shows and movies that are available to our members. We will add more than 500 titles May 1, but we also have titles expiring, this ebb and flow happens all the time.

We are selective about what’s available to watch on Netflix. We often license TV shows and movies on an exclusive basis, so we can provide a unique experience. We’ll forego, or choose not renew, titles that aren’t watched enough. We always use our knowledge about what our members love to watch to decide what’s available on Netflix. Our goal is to be an expert programmer, offering a mix that delights our members, rather than trying to be a broad distributor.
